Welcome to the Daily Mini Sudoku and Daily Mini Killer - bite-sized puzzles if you are too rushed to try a normal sudoku or killer sudoku.
Some of these are tougher than you might think. For the mini sudokus we are publishing three grades during the week - moderate, tough and diabolical.
The range of Mini Killers extends from 'Kids' level - a nice introduction to the puzzle - all the way to diabolical.
